Access fittings and valves cores. These devices allow you to load or unload the system, simply and quickly. once these loading or unloading operations are completed, a cap with gasket is available. Assemble the cap on the charge connection to prevent any possible loss of refrigerant. The device can also be closed using a blind union (article 31001) by interposing the truN.C.ated conical copper gasket with tang (article 31517). The mechanism housing, provided in the charging connections, is made according to the ARI STANDARD 720: 1997 standard. By screwing the mechanism inside the charging connection (according to the appropriate tightening torque), the passage of the refrigerant in the charging or discharging operations is obtained by simply operating the pin of the mechanism itself.
Service valve adapters and their mechanisms are designed for installation in cooling systems as well as domestic and industrial air-conditioning systems where refrigerants of Group II (as provided for by Art 13, Chapter 1, Point b of Directive 2014/68/EU, with rference to CE Regulation No.1272/2008 are used. Group II includes all refrigerants classified as A1 in annex E of EN 378-1:2008 standard. Thanks to these devices, the system can be quickly and simply filled and drained.
The main components of the service valve adapters in the 31500 series are:
Fitting body made of brass EN12164-CW614N or EN12165-CW617N
Copper pipe EN12735-1
Brass mechanism EN12164-CW614N with Neoprene, HNBR or EPDM gasket (depending on the model)
Brass caps EN12164-CW614N with Neoprene gasket
